I need regular blood tests. Among my many, many health problems I have heart failure and chronic kidney disease. I'm housebound and the nurses come to me to take blood.
They rarely get any but my potassium is abnormally high which the GP says is dangerous given my situation and they need to check it.
I drink as much water as I can possibly manage, I use a wheat bag on my arm and hand. When they have no luck with my arm they have a go at the back of my hand.
Is there anything else at all I can try? I do the things they suggest and out of the last 5 times they've been they got blood once and it wasn't enough to do the tests they needed to do.
They were here yesterday and got nothing after trying 3 places. They'll be here at about 11 to try again
